It's interesting, but the camera starts to feel quite disorienting after a while. There also isn't really much variation between the levels or enemies, so it's not really interesting past the first 15 minutes of playing.
Hitboxes are also a bit too stingy, especially for the rings. I managed to figure out the stealth part of it when I realized flapping seemed to alert them, but it was a lot easier to just fly straight at them than try to go around the buildings. Voice acting made me laugh when I first heard the "I hate vampires so much it's unreal" line though. I think leaning into that kind of tone would be good for this game.
